SlimFast is one of the bestestablished U.S. companies in this market, as they have been out there since 1972, although the main company was founded in the 1940’s. The Original Mix, however, was released in 1987, being one of the most popular products to date with a huge customer base. Later, they have expanded the brand to a comprehensive diet plan with several products, including snacks and bars. Let’s take a closer look at the slim fast shakes.

What is Slim Fast?

SlimFast is essentially a weight loss program. According to the company, its current version is the result of over 50 clinical studies that showed positive results in order to offer many different choices, including the slim fast smoothie, several slim fast protein shakes, cookies and even chips.

It is important to highlight that the company claims this product works best under certain parameters. Its recommended meal plan includes consuming two replacement meals each day and three snacks.

The slimfast diet replaces regular meals so that men’s intake can go down to 1600 calories and women’s fall to 1200. The goal is boost metabolism and decrease the calorie intake in a healthy way to promote shedding pounds. However, it does not mean that it is completely restricted, rather it provides a delicious set of options to suit the individual preferences.

Now, let’s get down to the Slim fast shakes. These are meant to replace meals -although not necessarily the main ones- in order to provide all the necessary nutrients the consumer’s body need to eliminate the cravings and hunger that usually drive people out of the plan.

The company offers several meal replacement powders for multiple diet plans, such as keto, diabetic, vegan, gluten-free, the original and many others. Their idea is to cover every target to promote weight loss among different groups.

What’s in The Slim Fast Shakes?

As it was mentioned before, this company offers meal replacement shakes but this article will focus on the Slimfast original shake mix.

In order to make this shake, the label recommends to mix it with 8 ounces of fat-free milk, so it is important to keep in mind that it adds some nutritional content to the powder itself. Now, although there is not a lot of info about the slim fast ingredients -as they try to keep the mix recipe for their own-, there are a few things that can be mentioned about its content.

Nutritional information

The label’s reference states that the information will be different when taking it with milk than when mixed with water -as milk increase the effects and results.


Getting enough energy to get through the day is important, especially if the consumer increases the weight loss effects with exercise. This powder provides a total amount of 110 calories on its own, while the slim fast shake calories amount is raised to 200 with milk.


This is probably the most important component in most meal replacement shakes, as it is one of the main ingredients that curbs hunger. In this case, the original mix offers 2 grams with water and 10 grams with free-fat milk.


This is the sum of both sugar and fiber. The amount of sugar contained in the shake is 11 grams, but it builds up to 24 grams with milk. On the other hand, the beverage will contain four grams of fiber in both cases. Although the amount of sugar is somewhat high, the fiber balances the deal, making the consumer feel more satisfied.

Minerals and vitamins

Although Macros are not as competitive as others in the market, its 26 micro nutrients will blow your mind. There are even vitamins that most shakes often do not include in their beverages, such as chromium or vitamin K.

Slim fast diet reviews report that users lose weight on a steadily basis of 1 to 2 pounds a week and up to 7% of fat. Although it does not seem like much, it promotes the diet consciousness and fosters healthy routines. Another important aspect to consider is the serving cost at $1.14, which is quite inexpensive in comparison to others in the market. In that sense, the slim fast solutions are considered a good deal.

Side Effects

Consumers should always consider the possible adverse consequences of any product. This powder is not the exception. In that sense, here are some details to take into account in regard to this shake:

Sweeteners and sugar

The Original Mix contains a considerable amount of sugar. In fact, if consumers do not control its sugar intake throughout the day, they could go over the recommended daily limit. In regard to the sugar-free versions,they contain certain sweeteners that could lead to stomach complains.

Sodium content

The shake contains lots of micro nutrients that are great to fulfill the body’s needs. Nonetheless, it also provides a considerable amount of sodium (14% of the recommended intake). Thus, users must be careful not to surpass their boundaries.

Bottom Line

Slim fast shakes are a great option as long as the consumer includes it into the recommended meal plan and exercise. Otherwise, it will probably not achieve the intended results or it could even bring negative effects. Also, it is important to check which powder is the most suitable for each case, maybe the Original Mix is not the best for a person with diabetes, for example. Finally, it is important to be conscious about the daily consumption when doing the slim fast diet, as it is what the company is trying to teach their clients.
